Training them to disarm traps could cause more harm than good. Training them to avoid traps would maybe be better. If poachers learn that their prey are hanging around the traps all day disarming them they become lures. We also don't want an arms race between poachers and trained disarmers because the poachers are at a massive advantage. Once they know a significant number of their traps will be disarmed they will just develop traps that are more difficult to disarm or even traps that hurt the animal attempting to disarm them at which point we've trained Gorillas to walk right into their traps.
